Abstract : In this paper, we propose a selective-forward-error-correction (S-FEC)scheme that allocates channel protection bits only to those packets that are in most need of correction. In this way, more available bits can be reserved for source coding. The degree of corruption contributed by a particular packet is measured by a similarity check function at the receiver, which does not require explicit knowledge of the source data. Simulation results and comparisons with existing FEC schemes are provided to illustrate the excellent performance of the proposed method.
